List-I | List-II |
A. Metacentric chromosome | I. Chromosome has a terminal centromere |
B. Sub-metacentric chromosome | II. Middle centromere forming two equal arms of chromosome |
C. Acrocentric chromosome | III. Centromere is slightly away from the middle of chromosome resulting into two unequal arms |
D. Telocentric chromosome | IV. Centromere is situated close to its end forming one extremely short and one very long arm |
The correct matches are:
A. Metacentric chromosome - II. Middle centromere forming two equal arms of chromosome.
B. Sub-metacentric chromosome - III. Centromere is slightly away from the middle of chromosome resulting into two unequal arms.
C. Acrocentric chromosome - IV. Centromere is situated close to its end forming one extremely short and one very long arm.
D. Telocentric chromosome - I. Chromosome has a terminal .
Therefore, the correct option is (4): A-II, B-III, C-IV, D-I.
Match the terms in Column-I with their description in Column-II and choose the correct option.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
